Neben Nikotin ist Pyrethrum das stärkste pflanzliche Insektizid; seine Wirksamkeit wird jedoch durch Sonnenlicht und Wärme verringert (Römpps Chemie-Lexikon, 8. Aufl. (1987) , S. 3414) . Der Mangel an Stabilität, aber auch der hohe Preis der natürlichen Pyrethroide hat zur Entwicklung zahlreicher synthetischer Derivate geführt.

Schaben und anderes Hausungeziefer, Motten, Kornkäfer, Moskitos, Garten- und Gewächshausschädlinge, Heu- und Sauerwurm im Weinbau und Baumwollschädlinge. Besonders die natürlichen Pyrethroide zeichnen sich durch einen raschen sogenannten "Knock down-Effekt" aus, d.h. die Insekten sind zwar rasch, aber nur vorübergehend gelähmt und erholen sich wieder. Verantwortlich für diesen unerwünschten Effekt ist der oxidative EntgiftungsstoffWechsel der Insekten.Insecticides used, especially against houseflies, cockroaches or cockroaches and other house vermin, moths, grain beetles, mosquitoes, pests in the garden and greenhouse, hay and sour worms in viticulture and cotton pests. The natural pyrethroids in particular are characterized by a rapid so-called "knock-down effect", i.e. the insects are quick, but only temporarily paralyzed and recover. The oxidative detoxification of insects is responsible for this undesirable effect.
Insektizide pyrethroidhaltige Zusammensetzungen gegen kriechende und fliegende Insekten werden üblicherweise in flüssiger Form auf die zu behandelnde Fläche mittels Druckgaspackungen oder Handpumpen gesprüht oder in Pulverform als Lockköder ausgelegt. Diese Anwendungsformen besitzen den Nachteil, daß beim Reinigen der behandelten Fläche die insektizide Zusammensetzung entfernt und zur Beibehaltung der gewünschten Wirksamkeit deshalb erneut aufgebracht werden muß, was zu einem großen Verbrauch an Insektizid und somit hohen Kosten bei Daueranwendung führt.Insecticidal pyrethroid-containing compositions against crawling and flying insects are usually sprayed in liquid form onto the surface to be treated by means of compressed gas packs or hand pumps or in powder form as bait. These forms of use have the disadvantage that the insecticidal composition must be removed when cleaning the treated area and must therefore be reapplied in order to maintain the desired effectiveness, which leads to a high consumption of insecticide and thus high costs for long-term use.
Zur Bekämpfung von lästigen Insekten und Parasiten bei Säugetieren, wie Stallfliegen, Hornfliegen, Zecken und Milben, können den Tieren beispielsweise Halsbänder aus porösem Material angelegt werden, die mit einer Pyrethroid-Zusammensetzung getränkt und mit einer Membran abgedeckt sind. Diese Zusammensetzung kann als Additive UV-Absorptionsmittel und Antioxidationsmittel enthalten (WO 85/03197) . Die beschriebenen insektizidhaltigen Materialien entlassen das Insektizid langsam an die Umgebung. Sie sind jedoch nicht geeignet, um beispeilsweise in Haushalten gegen kriechende Insekten eingesetzt zu werden, da sie zum einen zu dick und zum anderen durch ihren Schichtaufbau aus porösem Material und Membran zu empfindlich sind.To combat annoying insects and parasites Mammals such as stable flies, horn flies, ticks and mites can be put on the animals, for example collars made of porous material, which are impregnated with a pyrethroid composition and covered with a membrane. This composition can contain UV absorbers and antioxidants as additives (WO 85/03197). The insecticide-containing materials described release the insecticide slowly into the environment. However, they are not suitable, for example, for use in households against crawling insects, because on the one hand they are too thick and on the other hand they are too sensitive due to their layer structure made of porous material and membrane.
Aufgabe der vorliegenden Erfindung ist es deshalb, ein verbessertes insektizides Produkt zur Verfügung zu stellen, das auch gut gegen kriechende Insekten eingesetzt werden kann, das unempfindlich gegenüber Beschädigungen ist und dessen Wirksamkeit über einen langen Zeitraum genutzt werden kann.The object of the present invention is therefore to provide an improved insecticidal product which can also be used well against crawling insects, which is insensitive to damage and whose effectiveness can be used over a long period of time.
Diese Aufgabe wird durch ein insektizides Produkt der genannten Art gelöst, das dadurch gekennzeichnet ist, daß das enthaltene Antioxidationsmittel aus der Gruppe, bestehend aus Tocopherolderivaten, Ascorbylpalmitat und Citronensäureestern, gewählt ist.This object is achieved by an insecticidal product of the type mentioned, which is characterized in that the antioxidant contained is selected from the group consisting of tocopherol derivatives, ascorbyl palmitate and citric acid esters.
